Why does the male seahorse get pregnant?
One theory about why male seahorses carry the babies is that this gives the species the ability to create more babies quickly.

What is the only male animal that gives birth?
Male pregnancy is the incubation of one or more embryos or fetuses by male members of some species. In nearly all heterogamous animal species, offspring are ordinarily carried by the female until birth, but in fish of the Syngnathidae family (pipefish, seahorses and the leafy seadragon), males perform this function.
How does a sea horse mate?
When seahorses mate, the female inserts her ovipositor into the male’s brood pouch (an external structure that grows on the body of the male) and deposits her unfertilized eggs into the pouch. The male then releases sperm into the pouch to fertilize the eggs.

How does a starfish have babies?
Reproduction. Both male and female sea stars hold their sperm and eggs in pouches at the base of their arms.

The egg and sperm float until they meet up and the sperm is able to fertilize the egg.
What is the average lifespan of a seahorse?
